Ground Circuit Test

  1. Turn ignition switch to OFF position. Disconnect 7-pin Yellow connector AB1 from body wiring harness connector B140 (Legacy) or B58 (SVX). Connector is located behind left kick panel. Connect connector AB1 to connector 2A of Test Harness "A" (98299PA000). See Figure .
  2. Using an ohmmeter, check resistance between ground and terminals No. 17 and 18 at connector 5B of test harness "B". If resistance is less than 10 ohms at both terminals, go to next step. If resistance is more than 10 ohms at any terminal, repair body grounding circuit.
  3. Disconnect connector AB1 from test harness "A". Connect connectors AB1 and B140 (Legacy) or B58 (SVX) together. Disconnect 12-pin Yellow connector AB6 from control unit. Connect connector AB6 to connector 8B of test harness "B". See Figure . Using an ohmmeter, check resistance between ground and terminals No. 11 and 12 at connector 5B of test harness "B". If resistance is more than 10 ohms, replace air bag main wiring harness. If resistance is less than 10 ohms, replace control unit.
